Republican activist Shaun McCutcheon of Hoover, Ala. walks past the Capitol as he leaves the Supreme Court in Washington, Tuesday, Oct. 8, 2013, after the court's hearing on campaign finance. The Supreme Court is tackling a challenge to limits on contributions by the biggest individual donors to political campaigns. McCutcheon, the national Republican Party and Senate Minority Leader Mitch McConnell of Ky. want the court to overturn the overall limits on what contributors may give in a two-year federal election cycle.
